Sakani mamapu a mumsewu kuchokera ku Google Earth

Kudziwa kwathu, palibe pulogalamu (pano) yomwe imatha kutsitsa misewu ya Google Earth mozungulira. Ngakhale mutha kuchokera ku Open Street Maps, koyipa sikuti akuchokera m'mizinda yonse.

Koma ngati wina ali ndi chidwi m'misewu ya Google Earth, ndiye kuti njira yotuluka ndikuwatsitsa ngati chithunzi, kenako ndikuwatsimikizira ngati gehena. Nawa maupangiri kuti muchepetse kuchuluka kwa nkhanza:

1. Ikani chithunzi chakuda chakuda

Timachita izi, kuti chithunzi cha satelayiti chisasokoneze ndikusintha kuwonekera kwa misewu. Chithunzi chakuda cha bmp chimapangidwa ku Mspaint ndipo chimayitanidwa kuchokera ku Google Earth, ndikutambasula mdera losangalatsalo.

2. Tsitsani chithunzichi ndi Stitchmaps

Tsopano, mukugwiritsa ntchito Makhalidwe, tinasankha zojambulajambula zomwe zimatilola kuti tiwone malemba a makulidwe ocheperapo pamsewu.

Onani momwe, ngakhale Google Earth sinaone misewu yonse pamtunda wa chithunzicho, Stitchmaps ndizo zonse, timasankha kukwera kwake, pakadali pano mamita 384.

Chojambulacho chikatanthauzidwa, timayitanitsa kuti titsitse, ndikudikirira kuti zojambulazo zigwirizane. pamapeto pake timasunga ndi tiff mtundu, ndi fayilo yoyikira ya OziExplorer (.map). Chithunzicho chikuwoneka motere: chithunzi kumanja ndikukulitsa:

Monga chithunzithunzi, ngati ife tikufuna kutembenuza icho ku .ecw, mkati Global Mapper timabweretsamo, timapereka ziwonetsero ndikuiuza kuti ikonze kuchokera pa fayilo ya .map. Kenako itha kutumizidwa ku .ecw kuti igwiritsidwe bwino ndi pulogalamu ina.

3. Pangani ndondomekoyi ndi pulogalamu yamakono

Lembani mzerewu ukhoza kukhala wokhumudwitsa theka, ngati mukufuna kusuntha mofulumira, mungagwiritse ntchito pulojekiti yokhazikika, monga Microstation Descartes.

Zimamveka kuti fano la .ecw ndilotiferenced (ngakhale kuti likhoza kuchitidwa kuchokera ku Descartes), chomwe chimabwera ndikutembenuza chithunzicho kukhala vekitala, ndimachitidwe omwewo omwe timawonetsa mu positi lapitalo.

Chigoba chimapangidwa ndimayendedwe achikaso, ndi china cha imvi ndiyeno timawauza kuti asinthe kukhala vekitala yoyeretsa m'mutu. Gawo lomwe lembalo lilipo, vekitala silingapangidwe, tiyenera kupanga mgwirizanowu wapansi, ngakhale ngati mukufuna kupezerapo mwayi kwa a Descartes, ndizotheka kuti atembenuza matchulidwe onsewo kukhala imvi ya mseu, ndichifukwa chake tinazipanga zochepa. Ngati lembalo likuyenera kusinthidwa, gwiritsani ntchito lamuloli pazomwe mukufuna.

4 Ngati simukukhala ndi Microstation Descartes

Iyeneranso kugwira ntchito yofanana ndi AutoDesk Kupanga Raster, ArcScan, zobwezedwa GIS, ngakhale Corel Trace.
